1. A computer-implemented method, comprising:
configuring an image signal processor (ISP) of an autonomous driving vehicle (ADV) with a first set of ISP configuration parameters, wherein the ISP is used to process raw image data of an image sensor of the ADV based on the first set of ISP configuration parameters;
determining whether one or more criteria is satisfied, wherein the one or more criteria corresponds to an expected change in a characteristic of ambient light being perceived by the image sensor of the ADV; and
in response to determining that a first criteria and a second criteria of the one or more criteria corresponding to the expected change in the characteristic of ambient light being perceived by the image sensor of the ADV are satisfied, configuring the ISP of the ADV with a second set of ISP configuration parameters based on the second criteria having a higher priority than the first criteria, wherein the ISP is used to apply an image processing algorithm to raw image data based on the second set of ISP configuration parameters to generate an image.
